I had the good fortune some years ago to have a joke stolen from me and performed on TV by a comic I knew. At first I was upset, but then I realized that, poor etiquette aside, the guy was funny and he would’ve been on TV with or without my joke. I also realized that if I couldn’t immediately write several more jokes to replace it, then I wasn’t funny, and I had no business calling myself a comedian. So I forced myself to make a mental adjustment and decide that the guy had done me a giant favor. And he had. I became much less precious about material. Of course I’d be “proud” of a good joke, but I knew to thicken my skin and just produce. My silent motto when I began to encounter joke theft on Twitter was “Go ahead and take ‘em, motherf—er. Here come five more.” My goal as a comedian became to be a Delta Force Operator of humor that you could throw in an empty room with nothing and I could make something funny and kill people with it. This remains my goal.
